A 2-hour, 50-mark practical examination from the 2013 specification, taken instead of Unit 6, that tests the practical skills developed through laboratory work in Units 1, 2, 4 and 5. Every Chemistry Unit 7 A-Level question paper and mark scheme in the collection is listed below, from Edexcel.
Every question on the one Unit 7 paper here was read and tagged with the topics its marks credit. For each topic: how many papers have a question on it, and the marks those questions carry on a paper of 50. A part on two topics counts towards both. Read question by question: blind checks found 112 of 120 question parts tagged with the right topic (95% confidence interval 87.4–96.6%). How topics are found and checked
